SACK-CLOSING GRAPPLE.

SPECIFICATION forming part of Letters Patent No. 779,614, dated January10, 1905.

Application filed March 7,1904. Serial No. 196,832.

To a whom, it may concern:

Be it known that I, SYVER Lon, a citizen of the United States, residingat Minneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain new and useful Improvements in Sack-Closing Grapples;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My present invention has for its object to provide a simple, strong, andeflicient sackclosing grapple; and to such ends it consists of the noveldevices and combinations of devices hereinafter described, and definedin the claims.

The invention is illustrated in the accompan ying drawings, wherein likecharacters ingrapple closed and interlocked. Fig. 4 is a verticalsection on the line 00 00 of Fig. 8, and Fig. 5 is a vertical section onthe line 00 m of Fig. 3.

The numeral 1 indicates an ordinary sack. The numeral 2 indicates a pairof jaws pivotally connected at 3 and provided at their free ends withradial extensions 4, having backwardlyextended lips 5, which lips areturned backward in opposite directions and on the opposite sides of theradial portions or heads 4. The bodies of the jaws 2 are approximatelysemicircular, and their inner edges are preferably rolled or folded overat 6 to prevent them from cutting the sack. Short chain-sections 7 arepreferably attached to the free ends of the jaws-to wit, to perforatedextensions of the flat heads 4thereof. These chain-sections affordconvenient handpieces, which may be gripped in the hand. ithout thesehandpieces it would be very difficult to tightly close the jaws onto themouth of the sack. When the jaws of the grapple are placed looselyaround the gathered mouth of the sack, the

chains should be crossed in opposite directions, and by pulling on thesame the jaws of the grapple may be tightly drawn onto the sack, so asto engage the lips 5 with each other or with the edges of.theoverlapping heads of the jaws. The heads 4 of the jaws 2 are preferablyprovided with perforations 8, which are adapted to register when theends of the jaws are interlocked, as shown in Fig. 3. One of thechain-sections 7 is also preferably provided with a cotter or split key9, which is adapted to be inserted through the coincident perforations 8to more securely lock the grapple-jaws onto the mouth of the sack whenthe said jaws are interlocked, as shown in Figs. 3 and 5, at which timesaid perforations 8 coincide with each other.

The jaws 2 are advisably made of springsteel and are adapted to besprung sidewise, so as to permit the back-turned lips 5 to clear eachother and to be sprung into interlocking engagement with each other orwith the outer edges of the heads 4 at will.

When the jaws are drawn onto the closed mouth of the sack and the lips 5are engaged with the outer edges of the heads 4, as shown in Fig. 3, thegrapple is contracted to its smallest dimension, and at such time theperforations 8 register, so that when great security is desired thecotter 9 may be inserted therethrough, as shown in Fig. 5, or, ifdesired, the yoke 10 of a padlock 11 may be inserted through saidperforations, as shown in Fig. 1. WVhen the mouth of the sack is toolarge to permit the jaws to be drawn together, as shown in Fig. 3, thelips 4 may be interlocked with each other to hold the jaws onto thesack.

The device described, while of very small cost, has in practice beenfound extremely efficient for the purposes had in view. It may be veryquickly applied to a sack or removed therefrom and will lock the mouthof the sack with much greater security than when tied by a string orcord. Furthermore, the device may be applied to or removed from the sackas readily when gloves or mittens are worn as it may be applied with thebare hands. This is important in cold weather.

From what has been said it will be understood that the device describedis capable of modification within the scope of my invention as hereinset forth and claimed.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. A sack-closing grapple comprising a pair of jaws, pivotally connectedat one end, and provided at their free ends with the extensions 4:,having reversely-turned lips 5 on their inner faces, which lips 5 areadapted to interlock with each other or with the overlapped heads l,substantially as described.

2. Asack-closing grapple comprising a pair of jaws, pivotally connectedat one end, and provided at their free ends with interlocking parts ontheir inner faces and with looselyconnected handpiece extensions,substantially as described.

3. Asaclcclosing grapple comprising a pair of jaws, pivotally connectedat one end, and provided at their free ends with extensions 4:, havingreversely back-turned edges 5 on their inner faces, and perforations 8,and chain-sections attached to said extensions 4, one of said chainshaving a key 9 adapted to be inserted through said perforations 8,substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

SYVER LOE.
